    摘要: The present invention relates to a modified diene elastomer made up of: a) at least 55 wt%, relative to the total weight of the modified diene elastomer, of a species coupled by a functional group having a function with formula -SiOR, in which R is a hydrogen atom or alkyl radical, and optionally another function able to interact with a reinforcing filler, b) 5 wt% to 30 wt%, relative to the total weight of the modified diene elastomer, of a star species having three elastomer branches connected to a same silicon atom belonging to a functional group that may or may not have a function able to interact with a reinforcing filler, c) a level of less than or equal to 15 wt%, relative to the total weight of the modified diene elastomer, of a species functionalised at the end of the chain by a functional group having a -Si(OR)
    2 function, in which R is a hydrogen atom or an alkyl radical, and optionally another function able to interact with a reinforcing filler, and d) a level of less than or equal to 15 wt%, relative to the total weight of the modified diene elastomer, of a non-functional diene elastomer. This elastomer makes it possible to optimise the compromise between the creep of the elastomer and the hysteresis of the rubber composition containing it, which is fully satisfactory for use in tyre manufacturing.

    摘要: The invention concerns a modified diene elastomer comprising: a) at least 70% by weight, relative to the total weight of the modified diene elastomer, of a diene elastomer functionalised at one chain end with a silanol function or a polysiloxane block having a silanol end and having a polymolecularity index before functionalisation less than or equal to 1.6, b) more than 0 and up to 30% by weight, relative to the total weight of the modified diene elastomer, of a star-branched diene elastomer having a polymolecularity index before star-branching less than or equal to 1.6, the Mooney viscosity of said modified diene elastomer varying from 30 to 80.

    摘要: The present invention relates to a continuous synthesis method for a diene elastomer incorporating a step for modifying the diene elastomer in a functionalisation device, said step being characterised by: - a kinetic model according to which the ratio of the kinetic constants is greater than 1, and - a flow reflected by a residence time distribution in the functionalisation device expressed according to equations 1 or 3: (i) in a functionalisation device with at least one tubular continuous reactor or with at least one cascade of at least two stirred reactors (Eq. 1), (ii) in a functionalisation device that is a combination of device (i) and a device with at least one continuous stirred reactor, having a residence time distribution characterised by the following equation (Eq. 2), the device (ii) having a residence time distribution characterised by the following equation 3, which is the result of the convolution of equations 1 and 2 (Eq. 3).
